You can load the file by reinstalling the addon, or increasing the version number in inc/install.def.php (append .1 to the number after the SVN revision number, then for the next try change it to .2, etc. That way it'll work correctly once you overwrite with a newer official version)

Is there any Trick? I reinstall the AddOn and load up new Charakter Data but there are still no Keys listet. If there ist something wrong in the translation I sugest that just some keys would not correct captured, but there are no keys in the List.
